Explanation:

Most of what we call dirt is grease or oil which will not come off with just water. This is because oil and grease are non-polar, which means they will not dissolve in the water.
Soap can mix with both water and with oil because the soap molecule has two different ends, one that is hydrophilic (polar head) that binds with water and the other that is hydrophobic (non-polar hydrocarbon tail) that binds with grease and oil.
